Secondary Pedagogical Schools Students Professional Motivation and Attitude to Education in the Czech Republic

(in english) The diploma thesis deals with professional motivation and attitude to the education of secondary school students. The work is divided into theoretical and empirical part. The theoretical part is primarily focused on the issue of secondary education with emphasis on secondary vocational schools of pedagogy. Subsequently, this part defines the term "pedagogical worker" and the association with professional motivation and professional education. The aim of the research was to find out how students of secondary pedagogical schools assess their professional readiness and how their professional motivation changes during their studies. The data were obtained through a questionnaire survey that was given to students studying in the fields of preschool and extra-curricular pedagogy and pedagogical lyceum. The evaluation of the questionnaire survey found out the results that show predominantly the positive attitude of student's education provided by the schools within the study of pedagogy and their professional training. The results of the research show that the greatest importance for respondents is the ability to combine theoretical knowledge with practical skills, which means that the students also evaluate their studies very positively. The students see the greatest income in the..

Total carbon content and humic substances quality in selected subtypes of Cambisols

Cambisols cover an estimated 45% of agricultural soils in the Czech Republic. We aimed our work at stabile forms of organic carbon and humic substances quality in Cambisols under different types of soil management (grassland and arable soil). Object of our study were the following subtypes of Cambisols: Eutric Cambisol (locality Vatín – arable soil), Eutric Cambisol (locality Vatín – grassland), Haplic Cambisol (locality Náměšť n/Oslavou – arable soil), Leptic Cambisol (locality Ocmanice – grassland), Haplic Cambisol (locality Nové Město na Moravě – arable soil), Haplic Cambisol (locality Přemyslov – Tři Kameny – grassland), Arenic Cambisol (locality Pocoucov – arable soil), Dystric Cambisol (locality Sněžné – arable soil), Dystric Cambisol (locality Velká Skrovnice – arable soil), Dystric Cambisol (locality Vojnův Městec – arable soil). Non-destructive spectroscopic methods such as UV-VIS spectroscopy, synchronous fluorescence spectroscopy (SFS) and 13C NMR spectroscopy for humic substances (HS) quality assessment were used. Total organic carbon (TOC) content was determined by oxidimetric titration. Fractionation of HS was made by short fractionation method. Isolation of pure humic ­acids (HA) preparation was made according to the standard IHSS method.Results showed that TOC and humus content varied from 2.70 % (grassland) to 1.3 % (arable soil). Ave­ra­ge HS sum was 8.4 mg / kg in grassland and 6.4 mg / kg in arable soil. Average HA sum was 3.6 mg / kg in grassland and 3 mg / kg in arable soil. Fulvic acids (FA) content was 4.7 mg / kg in grassland and 3.7 mg / kg in arable soil. HS quality was low and very similar for all studied samples. HA/FA ratio low (< 1). HS absorbance in UV-VIS spectral range was low and similar in all studied samples. Higher absorption in this spectral range was closely connected with higher HS content. Also in 2D-synchronous fluorescence scan spectra similar shape of spectral lines was detected. Relative fluorescence intensity strongly depended on HA and FA content. Five main fluorescence peaks for HA and FA presence at λex./ λem.: 468/488, 482/502, 450/470, 376/396, 340/360 at constant difference of ∆λ=20 nm were measured. 13C NMR spectra of HA isolated from Eutric Cambisol showed low aromaticity degree and high content of aliphatic moieties. HA were young (= less aromatic compounds in HA molecule) and no differences in HA structure were detected to compare arable soil and grassland
